I did my transmission fluid and pan change (2006 LR3 with 290K miles) a couple months ago due to improperly torqued bolts about 56K miles ago, which lead to seeping and eventual bad shifting. The conversion had been done awhile back, but was the first time I’ve done the fluid and filter change on my own. I was able to use a buddy’s lift (Scully Offroad in Sacramento, CA) which made access a bit easier.
The big game changer for me was removing the transfer case mount bolt just aft of the transmission and using a transmission jack to raise the aft end of the transmission about 2 inches. Not only did this make removing and replacing the pan WAY easier, but also accessing those 4 or 5 bolts at the forward end of the pan was a lot easier too. I did not replace the harness plug, as it was not leaking. All shifting issues resolved.
Now I have my 2013 and 2016 LR4’s fluid and filters to change lol. Thanks for all the tips here, I’m sure it’ll make the process a lot easier!!
